The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the coordinate of the point be represented as B
The value of B = B ( -10 , -6 )
Now , the dilation factor is given by k = 1/2
So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get
The coordinate of the point B' after the dilation is
B' = B' ( -10/2 , -6/2 )
So , on simplifying the equation , we get
B' = B' ( -5 , -3 )
Hence , the point after dilation is B' ( -5 , -3 )

If each quadrilateral below is a trapezoid, find the missing measures.
#1
Answer:
C = 101
E = 46
Step-by-step explanation:
79 + 134 = 213
180 - 79 = 101 (C+F has to equal 180)
79 + 134 + 101 = 314
360 - 314 = 49 (trapezoids have a total degree of 360)
The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.
It is given in the picture that measures the angles of a trapezoid.
It is required to find the other angles.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.
We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°
We know in trapezoid:
∠C+∠F = 180° and
∠D+∠E = 180°
For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°
For ∠E = 180° - ∠E ⇒ 180° - 134° ⇒46°
We have another trapezoid JKLM in which ∠K = 83°
We know in isosceles trpezoid:
∠K = ∠J = 83° and
∠L = ∠M
∠L = 180° - ∠K ⇒ 180° - 83° ⇒ 97° ⇒ ∠M
Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

Two fair cubical dice are tossed. What is the probability that the sum of the numbers showing on the dice will be four?
Answer:
1/36
Step-by-step explanation:
since a dice has 6 side and you want to get the probability of one of the dice it would be 1/6. But you have 2 dice and you need them both to have a 4.so you would need to multiply 1/6 by 1/6.
Im pretty sure this is right, its been a while since i did probability, but i hope this helps :)

Write an expression equivalent to m + m + m + m that is a sum of two terms.
Answer:
5m
Step-by-step explanation:
add them and add 1
An expression equivalent to m + m + m + m as a sum of two terms is 4m.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is:
m + m + m + m
Equivalent expressions are expressions that work the same even though they look different.
We can combine like terms to simplify the expression:
m + m = 2m
Now plug in the expression of m+m in the given expression.
So the expression becomes:
m + m + m + m = 2m + 2m
Now we have expressed the given expression as a sum of two terms, which are both 2m:
2m + 2m = 4m
Therefore, an expression equivalent to m + m + m + m as a sum of two terms is 4m.

The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
Answer:
56πx² + 36πx + 6π square inches
Step-by-step explanation:
The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
The surface area of a cylinder is given as:
2πr(r + h)
The radius of a cylindrical gift box is (3x+1) inches.
The height of the gift box is twice the radius = 2(3x + 1) inches
= 6x + 2 inches
The surface area of the cylinder is:
= 2 × π × 3x + 1( 3x + 1 + 6x + 2) square inches
= 2 × π × 3x + 1(9x + 3) square inches
= 2π × 3x + 1(9x + 3) square inches
= 6πx + 2π( 9x + 3) square inches
= 6πx (9x + 3) + 2π( 9x + 3) square inches
= 56πx² + 18πx + 18πx + 6π square inches
= 56πx² + 36πx + 6π square inches
The surface area of the cylinder is 56πx² + 36πx + 6π square inches

find the slope of the line that passes through the coordinates (3,-6) and (-9,2)
9514 1404 393
Answer:
-2/3
Step-by-step explanation:
The slope formula is useful for this.
m = (y2 -y1)/(x2 -x1)
m = (2 -(-6))/(-9 -3) = 8/-12
m = -2/3
The slope of the line is -2/3.
__
The graph shows the two points and a line with a slope of -2/3.
can someone please help I need it right now!!
Answer:
y=9x
Step-by-step explanation:
First let's find the slope of this.
To find the slop we can take two points.
(1,9) & (3,27)
27-9/ 3-1 (slope equation) = 18/2=9
The slope of the equation is 9.
Now let's use point-slope form to find the equation.
(1,9)
y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)
y-9=9(x-1) (substitute m for the slope)
y=9x-9+9
y=9x
